The world-weary sadness of the ending prompted a deep, appreciative rather than excitable response.
Once affected, the mice are behaviorally abnormal as well, being initially excitable in response to stimulation and then lethargic (after approximately 15 weeks of age).
We also examined whether the neurons were excitable in response to exogenously applied neurotransmitters through electrophysiological studies.
Voltage-gated sodium channels are transmembrane proteins that allow fast influx of sodium ions into excitable cells in response to membrane depolarization, and are responsible, among other functions, for generating and conducting action potentials (reviewed in Ogata & Ohishi 2002).
In control conditions with excitable dendrites, the response in microcircuits of 150 cells was amplified by a factor of 2.3 compared with the response of single unconnected cells (Fig. 6 A, solid vs. dashed black curves).
Soon after the initial introduction and engineering of ChR2 for mammalian neurons [11], it was shown that the expression of ChR2 in a variety of organisms allows for the light-induced depolarization of excitable cells in response to blue (470 490 nm) light [8], [12], [13].
► Intramolecular interaction in LTCC C-termini with pharmacotherapeutic potential Voltage-gated calcium channels (VGCCs) govern important physiological functions such as contraction, secretion, neurotransmission, and gene expression in many different cell types by mediating Ca2 + entry into electrically excitable cells in response to membrane depolarization [1].
In the fully excitable network, the response rate increased linearly with number of cells activated (Fig. 5 B). Figure 5 B also shows that dendritic nonlinearity kicks in even when a small percentage of the cells are activated via the thalamic input (compare black and color lines).
We analyze spiking responses of excitable neuron model with a winding threshold manifold on a pulse stimulation.
Intracellular Ca2+ plays a major role in the physiological responses of excitable cells, and excessive accumulation of internal Ca2+ is a key determinant of cell injury and death.
